STMicroelectronics talks about smart meter communication and development
After the State Grid determined the development plan of the smart grid in July 2009, the development of the smart grid has become a key development area in China. According to the plan, during the "Twelfth Five-Year Plan" period, State Grid Corporation's total investment in smart grid power was 286.11 billion yuan, with an average annual investment of 57.22 billion yuan, a significant double of the annual investment of 25 billion yuan in the "Eleventh Five-Year Plan". As China's smart grid enters a period of comprehensive construction, stimulating smart meters also generates huge market demand. According to the "12th Five-Year Plan of Smart Grid", State Grid will install 230 million smart meters during the "12th Five-Year Plan" period only. According to the research report of GF Securities, from the perspective of the number of tenders in previous years, the bidding volume of smart meters from State Grid Corporation of China from 2009 to the first half of 2013 was 2.9 million, 45.37 million, 59.9 million, 75.93 million, and 45.72 million. The demand for electricity meters is stimulated by the transformation of rural power grids, new demand and renewal demand, and the total demand is very likely to exceed the original plan. Another brokerage researcher said that judging from the current bidding process, the bidding volume of smart meters has already exceeded 100 million, and this year's overall probability of exceeding 70 million is very high. The huge market potential has attracted many companies to intervene, and smart meter-related companies have also sprung up. Li Xiaoxian, Smart Grid Market Manager of Industrial and Power Devices Division of STMicroelectronics Greater China and South Asia, said that smart grid is one of ST's key areas. ST will work with our global partners to jointly promote the evolution of key technologies and provide the industry with advanced and reliable smart meter solutions. The smart meter chip ST75MM released not long ago is the world ’s first smart meter IC that supports the open communication standard of METERS & MORE. The new product will enable smart meter devices to achieve a wide range of interconnections through power line communication (PLC) technology, which will help promote Smart grids also bring maximum benefits to the environment, consumers and power supply companies. As an intelligent terminal of the smart grid, the smart meter is no longer a traditional energy meter. In addition to the measurement function of the traditional electricity meter's basic electricity consumption, the smart meter has two-way Intelligent functions such as rate measurement function, user terminal control function, bidirectional data communication function with multiple data transmission modes, and anti-theft function. It is very important to realize the intelligentization of electricity meters in the management and analysis of data and the interconnection of data, and the communication technology represented by carrier and wireless will be one of the fields of continuous and rapid development. Li Xiaoxian said that ST has long-term dedicated technical investment and experience accumulation in the field of smart meter communication. It launched the industry's first PLC communication chip in the 1980s and has become the largest PLC chip provider in the international market in more than 20 years. ST maintains close cooperation with many technology leaders and public utility companies in the industry, and has long-term experience in collaborative development and maintenance upgrades. ST uses its world-leading PLC, ARM Cortex-M MCU and other key devices to provide a variety of advanced overall communications solutions. ST75MM is a highly integrated power line carrier communication (PLC) system-on-chip (SoC) that fully supports METERS & MORE. METERS & MORE is an open and interconnected communication standard jointly promoted by multiple industry technology leaders and public utility companies worldwide. With millions of deployments and long-term field verification, it can effectively meet the challenges of smart meter interconnection and interoperability. With the development of smart grid construction and the increase of intelligent investment, in the future development process, smart meters will gradually replace traditional meters, but smart meters are also full of challenges while ushering in unlimited opportunities, such as using the most advanced technology and control The contradiction of investment cost, the contradiction between reliability, high efficiency, uniformity requirement and complex and diverse real environment. Li Xiaoxian said that ST, as a provider of smart meter chip solutions, actively promotes the development of new technologies, new solutions and advanced semiconductor processes, and provides world-class high-performance, highly integrated series products to help customers achieve the best investment returns. At the same time, ST will share experience with key partners to jointly promote the development and integration of smart meter standards. ST's main IC products such as PLC, metering, MCU, RTC, power supply, storage, RF, interface and other smart meters are used by system integrators in various environments around the world for a long time. Based on these extensive experiences, ST is confident to develop innovative products and solutions to face the challenges of new markets. After years of development, the Chinese electricity meter industry has moved from early induction meters, ordinary electronic meters, prepaid meters, and pay-rate meters to smart meters that meet market demands today. Today's smart energy meters not only have independent MCU, memory, hard clock, communication interface, load switch, and encryption unit, but also have functions such as energy measurement, fee control management, data freezing, data encryption, and event warning. The level of intelligence has been significantly improved . The future electricity meter will be smarter, more reliable, safer, with higher integration and interoperability, especially the communication technology represented by carrier and wireless will be one of the fields of continuous rapid development. Global smart grid upgrades are underway. With the investment of new technologies and large-scale system improvements, smart meters will better serve the environment and improve people's livelihood. The market prospect is quite positive. Smart meters represent the future development direction of smart terminals for energy-saving smart grid end users.
